Recover energy from gravity

[rc4]

had you try to understand second idea with pressure ? Entry a circular helix with gas inside, the lenght of helix is N*sqrt(r²+(p/2pi)²) with N the number of turn, r the radius and p the pitch. When the helix is inside container where there is 0 pressure, I transform the pitch to radius (volume = constant).

If there is a torque that change the shape of the helix,it would be better put she in a container ful of water,and varing the pressure by a weight on the surface...maybe...

if the diameter increase, this give energy from a torque (think about a helix with 2 ends, you will see that is ends that lost energy), sure I can't increase diameter from nothing all along the helix, but like helix has pitch length, I can reduce pitch so I can increase diameter. I don't think pitch lost energy because it's linear not circular. This need to be compute for verify.

Another idea with 2 spirals. One spiral turn clockwise, another turn anticlockwise. The container move down with a velocity relative of the angular velocity of spirals. The container move down with the additional volume from the black cable. Black cable is empty and has no weight in theory, in practice imagine it with very thin walls, and it is full of of air inside. Black cable give a up force, but this force is not give to the container, spirals control this force. Container move down with additional weight from the volume of black cable. Spirals turn only, they don't move down. Cable is rool up around red cylinder like a helix.

Second image: the cable slide only, cones don't turn like that no torque from up force inside water.

Watch this, quite an interesting and practical idea to convert gravity into light.

Best,
